are open to being a collector for a more kind of mobile system or a smaller subset. when you mentioned technology, i had forgotten to bring up that we have three reverse vending machines where you put your bottle in and get the nickel back, instead of the other way around. it's an old technology that didn't work to well in the '80s that has been revised. if you go to canada or europe, it's very common there, even on the east coast it's very common to. and they have gotten much better machines so you can now put a machine like that in front of the store. >> is that at whole foods at 4th street? >> no, it's at the safeway at 4th street and one at clement and 7th, safeway and one i believe at the marina safeway. >> are they being used? >> yes, they are. >> they are kind of limited, again, if someone comes up with a shopping cart it kind of shuts it down, but for the family or for folks, that is kind of the small-scale solution.
